Definitions

  • the invention relates to a snow sliding board and a method for its production according to the preambles of the independent claims.
  • snow sliding boards such as As alpine, cross-country, telemark or jump skis, big feet, snowboards, etc.
  • the latter differ in their structure and use from most other snow sliding boards.
  • Snowboards are wider than the other snow sliding boards. While most skis are strapped individually to one leg of the skier and therefore have to be available in pairs for use, only one snow gliding board is required for skiing, which, unlike other snow gliding boards, has two binding attachment areas. In contrast to other snow sliding boards, these binding attachment areas in turn have integrated recordings of the binding, so-called inserts.
  • a disadvantage of known snow sliding boards is their relatively high mass density of over 900 kg / m 3 and the resulting high weight.
  • For snowboards with typical dimensions such as 1500 mm length, 290 mm maximum width and 10 mm maximum thickness, this results in dead weights of over 3.2 kg.
  • Such heavy snowboards are tedious to carry, they have to be driven with great effort and they are slow to react when changing direction.
  • snow sliding boards with a low dead weight are sought, so-called light boards or light boards.
  • a solution for the construction of light boards is disclosed in the patent specification CH-686 028.
  • a light core with a density of not more than 400 kg / m 3 When using a light core with a density of not more than 400 kg / m 3 , light snowboards with average densities of at most 850 kg / m 3 are obtained .
  • Honeycomb materials or fiber-reinforced rigid foam are proposed as light core materials.
  • a first disadvantage of such light snow sliding boards relates to the absorption capacity of shear stresses between the outer layers as well as a low shear stiffness and the relatively poor damping behavior against vibrations and impacts.
  • Shear stresses arise, for example, from the bending of the snow gliding board under shear loading and impair its resistance to deformation or breaking and the driving properties. Vibrations and impacts result from external disruptive factors such as uneven slopes and bumps and reduce smoothness and edge grip.
  • Light core materials have low shear strength and a low shear modulus so that there is an inherent risk of breakage and cracking. Furthermore, (unreinforced) light boards dampen impacts poorly.
  • a second disadvantage of light snow sliding boards concerns the pressure resistance.
  • Light core materials have a low compressive strength and are compressible.
  • the compressive strength of honeycomb structures is greatly reduced when the component is highly deflected.
  • the distance between the belts changes, which in turn has a negative impact on rigidity, strength and bending strength.
  • a third disadvantage of light snow sliding boards concerns the power transmission to the snow.
  • a high power transmission from the feet via the shoes, bindings and straps into the steel edges enables precise steering and steering as well as quick maneuvers. For this reason, snow sliding boards with high strength are sought.
  • the document WO 97/06864 discloses a ski in which the binding carrier in the shell construction encompasses the core laterally, so that the binding carrier mechanically decoupled in this way resists twists and forces in the longitudinal and transverse directions of the snow sliding board. Viscoelastic damping layers are provided in the top chord in order to dampen vibrations and impacts quickly. This mechanically decoupled binding carrier also allows high power transmission into the running surfaces.
  • This solution with a mechanically decoupled binding carrier that encompasses the core laterally can only be used for relatively narrow skis. Snowboards, on the other hand, are much wider than skis, typically at least twice as wide. The lateral laminates absorbing the thrust are too small for snowboards; they would have to be reinforced, which leads to thickness and weight problems.
  • the document FR-2 667 536 discloses a snow sliding board in a layered construction with a core which contains a zone with a honeycomb structure which extends over its entire thickness and the rest of which is formed by a polymer mixture.
  • This snow sliding board also has the disadvantages described above - in particular low absorption capacity of shear stresses, low shear and pressure resistance.
  • the core is produced separately by placing the honeycomb structure in a mold and overmolding with the polymer mixture. After the core has been manufactured, the snow gliding board must be assembled from the core and other components. This multi-stage manufacturing process is complex and costly
  • the invention relates to snow sliding boards such as skis, big feet, snowboards, etc., but in particular to snowboards. This object is achieved by the invention defined in the claims.
  • the idea according to the invention consists in the development of lightweight components for static and dynamic types of loading, such as occur in particular with snow sliding boards.
  • This sandwich composite lightweight construction allows it to withstand high dynamic bending and compressive loads.
  • the reinforcement materials of higher strength are embedded in areas of very light core materials. It is advantageous to form a core matrix in which mainly very light core materials take on functions and are stabilized against bending, pressure and shear stresses by locally attached reinforcing materials of higher strength.
  • the resulting very light snow sliding board is characterized by a high shear and compressive strength, because the reinforcement materials of higher strength are embedded in recesses of the very light core materials in accordance with the main stress directions, in order to increase the core shear modulus, the core shear strength, the core compressive strength, the component rigidity and the component strength increase.

  • areas made of reinforcing materials are bonded to areas made of light materials by gluing.
  • the individual components of the core are preferably placed in a mold with all other parts of the snow sliding board and glued to the finished product in a single step.
